On the NHS, I tried for years to push for improvements to switch to digital cancer screening invitations after they missed my mother (offering to build the software for free), which is now happening, but suggesting the NHS isn't perfect is against the religion here. My sister who works in NHS DEI hasn't spoken to me since publishing a book on it.
Every time someone with the finances, vision and ability leaves I think the situation gets a little bit worse, it increases the proportion of people remaining willing to put up with all of it. Anecdotally, many of my friends have already left, some of the older generation want to leave but feel tied in. My flight out is in 6 weeks. Good riddance, no doubt.
Have they though about joining some sort of economic union, maybe one with like minded countries that share the same continent?
The EU might be better on digital privacy right now, however the emotional winds of the political mob change often and many people in EU government feel differently. The EU is also an aging population of technologically illiterate and immigrant-afraid retirees. I wouldn’t expect much different coming from them in the future.
Most of the OP's assessment that I quoted is about the UKs failing economics
Both have collapsing demographics, collapsing social welfare systems (turns out forced government pension payments thrown into low yielding bonds for people in their 20-30s who should be 100% equities is a bad idea), non-competitive taxation policy, and decades of underinvestment in risk assets that have starved their business community of capital needed to innovate or grow.
